SPEC continues to offer service support in dismantling and erection of concrete batching plants and mixers, in addition to offering concrete mix design.
We are specialize in the application of high quality waterproofing systems like liquid applied and pre-fabricated membranes, mainly for commercial and industrial projects. Our waterproofing treatments include terrace, wet areas, basement, swimming pools, below and above ground water retaining structures, etc.
Our expertise in flooring segment include high-end PU / Epoxy range of floor coating and topping systems, cementitious floor leveling systems and antistatic floorings.
The expertise in repair and protection we offer includes large volume and partial depth concrete repair with both cementitious and resin based systems. Structural strengthening and protection with CF laminates/wrapping, epoxy / PU based injection grouts and wide range of membrane forming / penetrative systems.
We undertake structural anchoring using resin based grouts; structural / machinery foundation grouting with epoxy resin and high strength cementitious / epoxy grouts.
We do undertake joint treatment using Field Modified Sealants (FMS) and Preformed Sealants.
Industrial flooring requires durable, long - lasting, resistant to abrasion and chemical actions, practical installation and endurance to harsh conditions.
Such a system is achieved through the Ucrete MF series - a BASF make. SPEC being proud applicators and distributors of BASF Materials have wide experience in Polyurethane industrial flooring.

Surface preparation to ensure proper results
The topping is properly mixed by skilled men to achieve homogenous mixing and is applied on the said floor
Surface preparation through scarification and Groove cutting
Prime/ Scratch coat application and Laying of the top coat
Method Statement for Heavy Duty Poly Urethane flooring using Ucrete
1. The area to be treated should be marked on the drawings and on the structure, or subject to revision based on conditions found as any breaking out proceeds.
2. All further repairs or re-bonding shall be at the discretion of the engineer and subject to re-measurement.
3. All deviations form the BOQ or the scope of work shall be agreed in writing by the engineer before reinstatement starts.
4. Proper vapour barrier should be present at the contact area between the concrete substrate and sub base soil which is an essential prerequisite for Ucrete flooring, which will give the floor topping long life, without which there are chances of the floor topping getting delaminated prematurely. BASF and applicator cannot be held responsible for the above incidence happening.
At the time of installation the concrete should have a minimum tensile strength of 1.5 MPa, be more than 7 days old and the surface should be dry.
1. Surface Laitance must be removed by mechanical action; suitable equipment such as grinding machine shall be used.
2. Locking chases to be cut into the substrate where not already present.
3. Locking chase must be present in the concrete within 75 mm of all free edges which may be cast into the floor or cut subsequently.
4. Chases should be included either side of all day joints in the substrate in preparation for a joint should movement subsequently occur.
5. At the soft joints subject to traffic and at channels, the chases should about the joints, to provide extra protection to the arise against impact and to prevent the ingress of liquids under the floor in the event of sealant failure.
1. Ambient Conditions: - The application should not proceed if the temperature is expected to be below the dew point at any time during the operation.
2. Primer/ Scratch coat: - Ucrete Primer SC should be mixed with an electric drill and mixing head and applied using a roller to the prepared substrate avoiding ponding, to provide a complete and continuous coating on the substrate.
3. Mixing of Ucrete MF shall be done using a forced action mixer and the mixing shall be done in whole packs. Nothing is to be added or left out.
4. The floor is laid at 4mm thickness with a wet front maintained throughout. The mixed material shall be spread out using a serrated steel trowel. A spiked roller shall be passed through the material to assist flow and release entrapped air.
5. The Roller should not be pushed through more than 10 cm into the previous mix.
Soil Stabilization using lime is an established practice to improve the characteristics of fine grained soils especially those soils having high clay – content.
Lime is a excellent solution for soil modification and stabilization. . Using lime can substantially increase the stability and load-bearing capacity of the sub grade.
Soil profile can be improved by the addition of lime which reacts with clay soil to form hydrated cementitious compounds that increases the stability of the soil.
Lime when added undergoes multiple reaction in which the main reaction includes - Flocculation, Cation – exchange and pozzolanic reaction which results in changing the properties of soil desirably.
Lime piles are installed at definite intervals specific to varying site conditions
The lime slurry once injected into the bored holes shall fill through the crevices in the soil subgrade.
The lime reacts with present aluminates and silicates to form hydrated pozzolanic compounds which results in improvement of soil bearing characteristics.
The key to soil stabilization is a reactive soil, a good mix design protocol, and reliable construction practices.
